STV8216

Audio Special Purpose Overview

The STV8216 is a single-channel audio signal processor and demodulator designed for consumer TV applications. It integrates a digital sound demodulator, DSP-based audio processing, and an audio matrix. The device supports I2C and I2S interfaces and operates on a 3V to 3.6V supply voltage. It is housed in an 80-TQFP (14x14) package with a surface mount mounting type. The operating temperature range is specified from 0°C to 70°C.

Audio Special Purpose Feature Summary

• Integrated NICAM, AM, FM Mono, and FM 2 Carrier Stereo demodulators for sound carriers between 4.5 and 7 MHz
• DSP-based audio processor featuring Smart Volume Control, 5-band Equalizer, Bass/Treble control, and Automatic Loudness
• Includes spatial sound effects such as ST WideSurround and Pseudo-Stereo
• Provides Subwoofer output with programmable bandwidth and headphone outputs with volume/balance controls

Audio Special Purpose Applications

• Consumer Audio
• Low-cost Stereo TV systems
• TVs with subwoofer and headphone capabilities

Audio Special Purpose Procurement Notes

The STV8216 is listed as an obsolete product by the manufacturer. Verification of current availability requires checking distributor status directly. As an end-of-life component, sourcing may be limited to existing stock or secondary markets. Designers should confirm lead times and authenticity through authorized channels before procurement.

Audio Special Purpose Selection Notes

Select the STV8216 for legacy TV designs requiring integrated demodulation and audio processing. Ensure the design accommodates the 80-TQFP package dimensions. Verify that the application environment stays within the 0°C to 70°C operating temperature range. Confirm compatibility with the required 3V to 3.6V digital supply voltage.

Audio Special Purpose Part Context

The STV8216 belongs to the STV82x6 family of multistandard TV audio processors. This family includes variants like the STV8206, STV8226, and STV8236, which differ in supported standards such as Zweiton, NICAM, and SRS 3D Surround. The STV8216 specifically lacks some advanced surround features found in higher-tier models but retains core demodulation and processing capabilities.

Audio Special Purpose Replacement Considerations

As the STV8216 is obsolete, no direct public substitute part numbers are confirmed in the provided documentation. Engineers must evaluate alternative audio processors or discrete solutions. Pin-to-pin replacements are not explicitly documented; functional equivalence testing is required for any potential swap.
